There are different types of chimney liners which you can use to line your chimney. When you are converting your wood burning fireplace to a gas burning fireplace and using the existing chimney as a vent, it is a good idea to install a flexible aluminum liner. You do not need to insulate the liner when using aluminum gas vent pipe.

Use Stainless Steel Chimney Liners with Today's Modern Fireplaces

Many older homes with fireplaces do not have any type of chimney liner installed because they have brick chimneys. However, with today's modern heating efficient fireplaces, it is important to install stainless steel chimney liners, available on our website, here at Copperfield Chimney Supply, which will fit into the existing brick chimney. You should also insulate the liner to ensure that temperatures are kept constant and insulation also helps slow down the buildup of creosote.
